Event driven communication between two scripts

3 posts in this topic

Hello,

I have two concurrent AutoIt processes.
Process "A" occasionally makes a change to the registry that I want process "B" to quickly pick up on.
I could get process B to check the registry value every 100ms. However, I would prefer a neater event driven way of getting process B to invoke a function that reads the registry value when process A changes it. i.e. Process A sets an event aswell as changing the registry.
Process B can't just sit waiting on an event because it has other work to get on with.
Is there a way I can achieve this with AutoIt?
Thanks

Kalavo

kalavo,

Search the forum for "Inter process communication". My personal favourite is MailSlot - you can read all about it in this thread, and I posted a test script in this one.

Thanks M23,

I did search before I posted but I guess I didn't look hard enough.

I think using WM_COPYDATA is going to be the best solution for my situation and have found a few examples on the forum.

Cheers
